Green Striped Cushaw Pumpkin
This grew vigorously in Colorado, beautiful spotted leaves.
Henry Field's 1941 Seed Sense and catalog said this "The neck is the edible part, is perfectly solid and of unusually high quality."
Space plants 18-24" apart with rows 6' apart. Wider spacing allows for easier harvesting. Plant/harvest radish prior to planting pumpkins can help for some insect control.
